Test release

dev: add test data for more RDNA2, RDNA1 and Sea Islands

v0.6.0

[0.6.0] - 2024-11-14

This is a big release, adding several new major features:

• Nvidia support! LACT now works with Nvidia GPUs for all of the core functionality (monitoring, clocks configuration, power limits and fan control). It uses the NVML library, so unlike the Nvidia control panel it doesn't rely on X11 extensions and works under Wayland.
• Multiple profiles for configuration. Currently it is not possible to switch them automatically, but they are configurable through the UI or the unix socket.
• Clocks configuration now works on AMD IGPUs (at least RDNA2). Previously it was not parsed properly due to lack of VRAM settings.
• Zero RPM mode settings on RDNA3. Currently this needs a linux-next to be used, and the functionality is expected to land in kernel 6.13. But this resolves a long-standing issue with RDNA3 that made the fan always disabled below a certain temperature, even if using a custom curve.

There are many other improvements as well, such as better looking and more efficient plots rendering in the historical charts window (thanks to @In-line ) and a Fedora COPR repository providing LACT packages (currently in testing).

v0.5.6

[0.5.6] - 2024-09-22

This release has two main features: custom power profile heuristics and support for remote management over TCP.

Parts of the UI have also been ported to use the relm4 library. This doesn't affect UI looks in any way, but allows for better structuring of code and is less verbose compared to using gtk-rs subclassing for custom widgets.

New power profile heuristics UI:

To set up remote daemon access see this README section.

v0.5.4

[0.5.4] - 2024-04-22

Major new features:

• Historical charts

  Added a dedicated window that shows clockspeed, temperature and power usage values over a period of time.
  Thanks to @In-line for the initial implementation.

• Fan control hysteresis

  There are two new settings for custom fan curves: spindown delay and speed change threshold.
  These settings help avoid unwanted fan speed changes caused by small temperature changes and short temperature drops (such as during a loading screen in a game for example), reducing fan noise.

• VBIOS dumping

  It is now possible to dump the current GPU VBIOS into a file (the option is in the dropdown menu).

• Automatic config reloading

  Now when you manually edit the config file in /etc/lact/config.yaml, LACT will automatically apply the changes. This can be useful in headless environments.

There are also some hardware handling fixes and usability improvements, see the full changelog below.

If you want to support the development of LACT, please consider sponsoring.
